IMPROVEMENT lN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 215,702, dated Ma'y 20,1879 application filed May 25,1878.

To all whom it may concern Be it known that I, PORTER WILLIAMS, of thecity of London, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements on Spring Bed and Lounge Bottoms andI hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, where Figure 1 is a perspective view of my invention. Fig. 2is a sectional view of one pair of springs, a portion of frame, andslat.

My invention relates to improvements in bed and lounge bottoms whereinthe mattress or other covering is supported on longitudinally-arrangedslats, each of which is carried by a pair of stout coil-springs,supported at head and foot in a common block, each slat being allowedindependent motion of the others.

A A are the slats, arranged lengthwise of the bed or lounge, as shown. BO are transverse npright blocks attached to bedstead or lounge, at thehead and foot, immediately above the ends of the slats. These blockshave a series of grooves or arbors, D, bored in themtwo to each end ofslat; and in these grooves are placed stout tapered coil-sprin gs E, sothat These coilsprings are larger at the base than at the top, and theyrest upon the bottoms of the arbors, where the circumference of the boreis reduced considerably.

F is a short length of strong wire, which passes under the end of eachslat, and both ends F F, being bent upward at right angles,

are passed through the small holes underneath the blocks, and carriedthrough the thus obtained, while lateral motion is almost whollyavoided.

A cover, G, fits closely over the top of each block, excluding dust,insects, &c., from the grooves.

I am aware that it is common to suspend slats bymeans of single rods andspiral springs; also, that longitudinal slats have been supported onbars extending across the bedstead at head and foot, said transversebars being suspended by spiral springs; aud, further, that slats havebeen attached by hooks to stirrups strained in horizontal position byconnectingrods and paired spiral springs. These forms, therefore, I donot claim.

What I claim is- The combination of the longitudinal slats A,

the stirrups consisting of the horizontal bar F and hookedsuspension-rods F F, the paired coil-springs E E, the grooved blocks BO, and the covers Gr, all substantially as and for the purposes setforth.
